T0 ctZZ whom it may concern:

Be it known that I, JOHN C. l-IEILMANN, .112, a citizen of the United States, and a resident of Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvementsin Candy-Forming Machines and I do declare the following to be a description of the invention sufficiently clear, full, and exact to enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings,with thereference-numerals marked thereon, which form also a part of this specification.

This invention relates to machines which by a rolling operation form' pieces of uniform size and shape out of a material which is of plastic or dough-like consistency. Machines of this kind are used in connection with the manufacture of confectioners and bakers goods, and my invention is described as intended for such purpose.

It consists of a certain device whereby the material to be worked up and formed into pieces is supplied in fixed and measured quantities, so that the resulting forms and objects are all perfectly alike as to size and shape.

My invention consists, further, of the construction of this device and of certain details of construction of other parts of the machine, all as more fully set forth hereinafter.

In the following specification and particularly pointed out in the claims at the end thereof is found a full description of my in- Vention, together with its operation, parts, and construction, which latter is also illustrated in the accompanying two sheets of drawings, in which Figure 1 is a front view of the machine. Fig. 2 is a top View thereof. Fig. 3 is an end view showing the left end as viewed in Fig. 1. Fig. 4 is a rear View of the left portion of Fig. 1. Fig. 5 shows a part of the machine in a sectional View taken on a plane passing across the discharge-outlet of the receiver.- Fig. 6 is a sectional detail view of the measuring device.

The mass or dough to be worked up is fed from a receiver 8, to which it is supplied through a hopper 9, which forconvenience of filling is surrounded by a pan-shaped shelf 11. After the hopper is filled a plunger 12 through a discharge-opening 15 in one of its ends, being moved by means of a screw 16, mounted upon a shaft 17, supportedin bearings 1O and 20, of which the first is formed in the other end of the receiver. Shaft 17 is driven from shaft 18 by means of gear connection 19, of which latter there is preferably a set of graduated sizes, as shown, to provide for adjustment of speed. The gear-wheels of the set on shaft 17 are loosely mounted; but any one of them maybe positively connected by means of a sliding key (not shown) operated for adjustment by means of a rod 21 and a lever 22, which is then looked in position, the whole beinga well-known expedient. Shaft 18 constitutes the drive-shaft of the machine and may be operated in any suitable wayas, for instance, by'means of a pulley 23. The mass discharging from opening 15 enters a measuring-cup, (see Fig. 6,) the bottom and side of which are formed of two independent members. The bottom is formed by the end of a stud 24, supported in a bearing 25, and the side is formed by a hollow cylinder 26, fitted to and mounted on stud 2A in a manner to be capable of a sliding motion thereon. There is a certain distance between the end of this stud and the discharge-opening of receiver 8, which space when the cup is to be filled is bridged by cylinder 26. The parts remain in this cup-forming position a certain length of time, which is sufficient for the cup to become filled, a certain part-say about half or more or lessof the revolution of the ma chine being apportioned for such purpose. After that the movable part of the cup recedes from the opening of receiver 8, leaving its contents unsupported, as shown in Figs. 1 and 2. At this time a rotating knife .30, mounted by means of a hub 27 on shaft 18 and driven thereby, passesclose in front of discharge-opening 15, cutting ofi theexposed mass protruding therefrom and causing the same to drop off from the end of stud 24.

This end is undercut, as shown, to facilitate the cut-off portion of the mass to clear the same. The detached piece drops first into a hopper 28, by which it is guided into the forming device, consisting of two complementary parts, between the oppositely-concaved surfaces of which the piece now is rolled to the desired shape. These parts consist, on the one side, of a roller 29, containing in its concaved face one of the forming-surfaces, while the opposite forming-surface, acting in conjunction therewith, is contained in a stationary concaved or gutter-shaped structure 31, fitted closely to and following to a certain extent around the periphery of roller 29. This forming-gutter is supported by a bracket 32, secured to the machine-frame. To facilitate entrance of the dropping-piece between these forming-surfaces, I provide an additional roller 33 above the upper end of gutter 81 and below hopper 28. Its face is opposite the face of roller 29 and correspondingly concaved, so as to act in conjunction with the other forming-surfaces. The shape of the pieces to be formed in this case being a ball, the forming-surfaces are each shaped accordinglythat is, the faces of rollers 29 and 33 and the inner surface of structure 31, the one opposite roller 29, are each concaved semicireularly. \Vhile the cut-off piece is thus given its shape by being rolled between the forming-surfaces, the measuring-cup is filling again, cylinder 26 having meanwhile returned to form such cup again. It is evident that during the time while the cup is not in position discharge-outlet must be closed,which is done by knife while passing close in front of this opening and is of sufficient width to remain in front thereof until cylinder 26 has returned and re-formed the cup.

To prevent adherence of the mass to the forming surfaces while being rolled between them and to facilitate this operation, I provide a device which supplies a suitable medium, like powdered starch or flour, to these surfaces. It consists of a receptacle 3't,supported on a standard 35 and so located as to bring its perforated bottom above roller 29, upon the face of which its contents are sprinkled. The discharge of the sprinkling material is effected by an agitator 36, operated by gear-wheels 37 and 38.

The different parts of the machine are driven from shaft 18, which is supported in bearings 39 and, as already stated, drives screw-shaft 17 of the feed device by means of gear-train 19 and has also knife 30 mounted on it. By means 'of bevel-wheels 41 it operates a shaft 42, supported in bearings 43 and which drives the other movable parts of the m. chine. By means of gear-wheel 38 it operates gear-wheel 37 on the agitator-shaft of the sprinkling device. By means of a sprocketwheel 4t and a chain 45 it operates rollers 29 and 83, which for such purpose are each re speetively mounted on one end of shafts 46 and 47, eachsuitably supported, and the other ends of which shafts carry each a sprocketwheel numbered, respectively, 48 and 49, each also engaged by chain 45. 51 is an idler sprocket-wheel the function of which is to chan ge the direction of motion of the sprocketehain. The movable part 26 of the measuring-cu p is reciproeated by means of a cam 52, acting upon a lever 53, the forked end of which engages said part 26. This lever is supported on a post 5t and held in contact with cam 52 by means of a spring 55. In place of the cam shown one with a groove receiving the end of lever 53 might be used, in which case spring 55 would not be required. The connection of this lever to part 26 is such as to permit ready removal of this latter in cases when pieces of different sizes, requiring more or less material, are to be dealt out. Stud 2t and the end of receiver 8 containing the discharge-opening are also removable for such purpose. The parts of the forming device, rollers 29 and 33, and gutter 3.1 are also interchangeable in case pieces of different size or shape are to be produced. IIopper 28 is also arranged to follow these adjustments, for which purpose it is in two parts, each secured by set-screws, so that its sides may be moved to or from each other.

To prevent adherence of the mass to the knife, the same is caused to pass at every revolution through a water-containing tank 56, whereby the blade is kept smooth and clean. Splashing of this water is prevented by fenders 57. 'More or less of this water on the blade of the knife is apt to be transferred onto the material, wetting the cut-off pieces to some extent, for which reason they are caused to discharge first upon the perforated surface of a drainer 58. This surface is inclined, and while the formed pieces roll down thereon the water is given a chance to drain off, the collected drainage passing away through a waste-pipe 59.

The pressure of the feed-screw within receiver 8 causes a separation of more or less of the liquid matter from the more solid substances, which liquid collects in the lowest part of the receiver, from which it is drained by a pipe 6l,which discharges into a vessel 62.

Having described my invention, I claim as new- 1. In a forming-machine, the combination of a receiver 8, having a discharge-outlet 15, a feed device causing the contents of the former to pass through this opening, a forming de vice, acup-shaped measuring device interposed between this latter and receiver 8, and means to cause it to travel with a reciprocatory motion to a position opposite opening 15 to be filled therefrom and afterward to recede from it, and to deliver its contents to the forming device.
